Abstract
Methods of producing coolant-cooled heat sinks with a coolant-carrying compartment between a cover and a heat transfer base are provided. The heat transfer base includes a heat transfer surface to couple to a component to be cooled, and a plurality of thermally-conductive fins extending into the coolant-carrying compartment from a surface of the heat transfer base opposite to the heat transfer surface. The method includes positioning a screen with openings over the plurality of thermally-conductive fins, between the plurality of thermally-conductive fins and the cover, and providing a joining material over the screen, between the screen and the cover. The method also includes joining the plurality of thermally-conductive fins to the cover across the screen using the joining material, where the screen facilitates retaining the joining material over the plurality of thermally-conductive fins during the joining.
